FAQ: Logic and Voltage Translation > Ground-Level Translators >> Current FAQ
TXG devices (both push-pull and open-drain) cannot support any level of IEC-ESD. However, IEC-ESD can still be achieved by using a protection device like the ESDS30x product family.
The ESDS30x family can support ±30kV contact and air gap discharge. The only drawback is the DC breakdown voltage of 4.5V (min). There is a possibility these device will start to breakdown before reaching 5.5V which is the max recommended voltage condition.
